How much Sr-90 in clip-on lights?

[avest@magnus.acs.ohio-state.edu (Albert Lee Vest)]

Like the subject says.  We recently found five of these in a steel pig in a
physics department lab.  Two are 1" diameter, three are 2" diameter.  All
are in sheet-metal cases, painted black but deteriorating, and have the
engravings "USRC" and "Poison Inside."

[They don't say Sr-90, but the GM tells me it ain't tritium.]  In order to
dispose of them, I need to know how much activity is probably contained in
these items.  Please answer if you can.
